『 此次发布是 Apollo 自 1.0.0 以来的又一次大版本更新，凝结了 39 位 Contributor 的贡献，包含了诸如 Java 17 支持、唯一键索引增强、Spring Boot 版本升级等重大更新。』

 

1. Highlights

Java 17 支持

Apollo 客户端和服务端均已支持 Java 8、11 和 17 版本。

公共 Namespace 列表页

Apollo 主页新增了公共 Namespace 列表视图，用户可以在此页面上查看和搜索公共 Namespace。

灰度发布支持标签

灰度规则支持通过标签来标识灰度的实例列表，适用于 IP 不固定的场景如 Kubernetes

配置导入导出功能增强

批量配置导入导出功能进行了重新设计并增强。

每个 Namespace 下现也已支持单独导入和导出。

唯一键索引

由于软删除的设计，Apollo 之前版本的数据库除主键外没有唯一键约束，在一些并发的情况下可能会遇到重复数据的问题。基于 2.0.0 版本新增的 DeletedAt 列，我们为大多数表都增加了唯一索引。

Spring Boot 和 Spring Cloud 版本升级

Apollo 服务端的 Spring Boot 和 Spring Cloud 分别升级到了 2.6.6 和 2021.0.1 版本。

不兼容更新 

apollo-client 从 2.0.0 版本开始不再支持 Java 1.7 版本，最低的 Java 运行时环境是 1.8。
